T0 or whom it may concern:

Be it known that I, EDGAR F. BELDING, of Fitchburg, county of Worcester, State of Massachusetts, have invented an Improvement in Counter-Skiving Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to construct a machine for skiving counters for boots and shoes.

In accordance with this invention an oscillating mold is employed, together with recip rocating feed -wheels. Independent springactnated pressers are also employed, which, by hearing down or pressing upon the counter, press it into the mold, so that its edges only may be exposed to be shaved off or skived. A quick-return crank-motion is provided by which the oscillating mold may be moved for ward slowly, thereafter to its normal position or starting-point quickly, the counter being placed in and fed upon the mold during its forward movement. The counters to be fed forward and skived are placed in a pile and the undermost one removed at each oscillation of the mold by suitable plates or blades mounted upon a carrier which is driven by the quickreturn crank-motion. A knife is adjustably secured to a frame which is pivoted ina holder mounted upon suitable shafts having eccentric hubs, to be described, whereby the said holder may be rocked and the knife thereby raised and lowered, and, in addition to such adjustment, the knife is made adjustable toward and from the mold.

Figurel showsa front elevation ofa counterskiving machine embodying this invention; Fig. 2, a top or plan view of the machine shown in Fig. 1; Fig. 3, a rear side view of the machine shown in Fig. 1; Fig. l, a left-hand end view of the machine shown in Fig. 3; Fig. 5, a detail of the mold, the reciprocating feeding devices, and the frame in which the counters are placed; Fig. 6, a sectional detail of the quick-return crank-motion; and Figs. 7 and 8, sectional details of the knife-holder, to be referred to.

The main frame-work A is of suitable shape to support the working parts. The shaft a,

mounted in the framework A, has fixed to it at one end the toothed sector a, and also at an intermediate point has fixed to it a counterreceiving mold, a The toothed sector a meshes with the teeth of a wheel, a fixed on a shaft, a, which shaft also has its hearings in the main frame-work A. Upon the shaft a are also secured several toothed or serrated feed wheels or surfaces, a herein shown as twelve in number, and placed ashort distance apart. The sector a is connected to a crankarm, I), by a link, I), and said crank-arm b is fixed to a shaft, 6 having its bearings in the main frame-work A. A circular hub, Z1 is also secured to the main frame-work,(see Figs. 3 and 6,) the center of which is eccentric to the pivot I) of the crank-arm b. A toothed wheel, 0, is loosely mounted upon the circular hub [2 said toothed wheel having projecting laterally from it near its periphery a pin, 0', which enters a block, 0, fitting and sliding in a guideway or slot formed longitudinally on the under side ofthe arm I). A toothed wheel, 0, is fixed to a shaft, 0, having its hearings in the frame-work, said shaft c"also having fixed thereon the drive-wheels 0 It will be seen that as the driveshaft a is rotated the toothed wheel 0 will in turn be revolved and the crank-arm b be moved on its pivot 12 by the pin and slide-block c c", and that the toothed sector a. will also be thereby oscillated by the link and crank-arm, as described. It will further be seen that by the construction of the crank and its operating parts, as shown and described, a quick return cranlemotion is formed, by which the sector a will be moved in the direction of the arrow thereon slowly but will return quickly.

At the opposite side of the machine (see Fig. 1) a crank-arm, d, is fixed to the shaft b", and is connected by a link, (1 with a horizontally movable carrier, (1. Th e carrier (1 has a groove upon its inner side, which fits a doitotail projcction, (2, formed upon theside of the namework A, which projection serves as the guide therefor. A plate, (1", is secured adjustably upon the carrier d by set-screws diwhich pass through slots (1, cut in said plate zlfland thence into the carrier, the slots at extending in the direction of the length of the plate 11, thereby affording longitudinal adjustment.

Two blades, e e, bent at right angles, as best shown in Fig. 2, are adj ustably secured to the plate 61* of the carrier by setscrcws 0 which pass through slots in said blades and into the plate. The ends of the blades e e are made ICO thin and arranged to follow closely upon the upper surface of the bed or table of the machine upon which the pile of eountersf to be skived is placed.

The counters f to be skived are held in place in a frame composed of four posts, 2 3 et 5, rising from plates 6 7 S 9, each of which plates is adj ustabl y secured by set screws to the blocks 9 g, which are supplied with guide pins 9 the heads of which pins enter dovetailed or, it may be, T-shaped grooves 9 cut in the upper surface of the bed or table.

The blocks 9 g are adjustable longitudinally and the plates 6 7 8 9 transversely, so as to provide adjustment for counters of different sizes and thicknesses.

As the counters are fed forward by the blades 6 0 they pass beneath the reciprocating feed-wheels a and the oscillating mold a", and are pressed down into the recess in the mold by a series of presser'feet, 2, herein shown as bent levers pivoted at 73', the horizontal arms of which serve as the presscrfeet, and the upwardly-extended arms of which are connected with adjusting screws 2' by springs 13", so that the tension of the presser-feet may be varied at will.

One presscr-foot is shown as placed between each feed surface a and acts to press the counter into the recess in the molds, leaving exposed above the surface of the mold the edge to be skived or shaved off.

The knife If; is secured adjustably by screws k to a plate, k, said screws passing through slots is in said knife. The plate It" is pivoted upon the rod 7c",having its bearingsin theframe k. The rear end of the frame is slotted to receive eccentric hubs of a shaft, 7a, to which shaft is fixed the hand-piece'k so that by turning the said shaft k the frame It will be raised and lowered on its pivot M.

The knife thus far described may be adjusted toward and from the presser-feet, and also may be raised and lowered as desired.

The plate is is held in the frame 70 which frame has two cars, upon one side and two cars, is", upon the other side. The cars k k have holes through them, which receive shafts n a. Each shaft n nhas two eccentrically-arrangedhubs thereon,whieh enter diagonal slots or passages a a cut in the ears, respectively. Toothed sectors a are fixed to the ends of the shafts a a, which are engaged by worms 02 formed on or secured to the shaft a, which is'adaptcd to be rotated by the handpiece a.

' When the hand-piece a is turned in one direction, the sectors a are moved simultaneously in one direction and the shafts n n rotated, so that the eccentrically-arranged hubs cause the frame is to rock in one direction, and by turning the hand-piece n in the opposite direction the frame k may be rocked in the opposite direction.

The frame 75 and pivoted plate 75 form the knife-holder.

I do not desire to limit my invention to the precise construction of some of the principal features of this invention, as the same may be modified and yet carry out the desired results.

I claim- 1. In a countcr-skiving machine, the oscillating mold a and the independent springactuated presserfeet, combined with the reciprocating feed wheels between the said presscrfeet and the knife, substantially as described.
